Set your Instant Pot to Saute. Pour in olive oil, onion, and garlic and cook until the onion is translucent.
Add Pork, sweet potatoes, tomatoes, chicken broth, and hominy.
Add chili powder and cumin
Close your Instant Pot and cook on the soup setting for 15 minutes.
Let the stew naturally release. Serve right away. Cheese or Sour cream would make an excellent garnish.
